BURKE. a

yc-iti zeh'fofthe united States, residing at Philadelphia, iii the county of Philadelphia,

State of Pennsylvania, have invented certain new-linduseful Improvements n Folda'nd Guiding Devicesfor Sewing-Ma chines, of which the 'followin is a descrip tion, reference being had to t e accompanying drawing had to the letters and figures of'reference marked thereon.

Tl 'sinvention relates to sewing machines and is designed particularly as an. improve ment upon theruiiiing sewing machine forwhich U. S. Letters Patent-were granted to Russel G. Woodward, oxrJuly 31, 19O0,-Z\o.v (5555143.

The principal object cf theinvention is 1 to, rovidea folding guide by means of which. ae double hem orpocketmay formed-at the edge of one piece of fabric,

-whilei'a'second-piece is rulfled and inserted therein.

f'Af -further object of.,the*inventihn is to providean improvedsectional folding, guide whichmay he opened to facilitate the. in-

troductionof the fabric.

, pended claims.

The invention consists'in the novel. construction and arrangement of parts hereinafter described and referifed to .in. the ap- In the accompanying draiivings, which illustrate the invention, Figure 1 is a side elevation of a sewing machine showing a 'folding guide constructed .in accordance Fig. 2 is a transverse sectional view, of the parts above the cloth with the invention.

The construction of themachihe proper is similar to that of the wellknown two line" manner to transmit movement tothe 23, which car'rimthe milling blade25, the

act thereon At the front of the cloth late is secured a la 10 which carries-w oldng gu de form iii-the present instance, in sections 11 and 12, thesection=12 being.

movable relatively to the section 11, so that the guide may :opened to facilitate the introduction of the. fabric. The movable stance. on a slidahle plate 15, the edges of which are adapted to guides'lfi carried by the plate '10,":md said late 1513 connected 1 o to .a plvotally mounte .0 rating-leverl7 A-stillfurthei ob ect of the invention is:

by means of a link 18. V e. lever- .i is pref section 12 is monnted,.in"the present in cmhly provided with..a handle. arranged,

within convenient reachof the operator, and while thehandle and plate 15 are shown above the ,car ing plate, they maybe readily arr-en ed: ow the same if found desirable. It will thus be seen that I have provided a guide with a movable section which may be withdrawn from the station any section'for the insertion of the febricf. Y

it will be notedthat the edges otthe sta. tionary and the movable sections of the guide, when in closed position, shown in l igs. 5. 6 and 7], are in-(xintact, and that I these edges, therefore, serve as sto s to suitahly space the sections of the gui 0, so that. v. a proper guiding space maybe formed for g the fabric.

Before proceeding further with the do" script-ion of the mechanism reference is had to Fig. 8 which shows the product of the machine, and from an examination of this operation of the folding guide will be hotter understood. The main fabric a; being part of a skirt or other article, is folded at b, and the fabric is thence folded again at c and again at d, the last fold hei to turn in the raw edge This forms w at f'h'rined for convenience, a double twegn b and'd and in the ocket or ace' between these islfd theiru estrip e, -rwhioh,-' however, does not extend to the bot- ".tom of the pocket. The fabric is stitched,

there being two distinct lines of stitching f g, the stitches f passing through the fabric a alone, while the stitches. 9 pass through both fabrics, bending down the double hem. and'securing the ruffle strip in place... f Referringnow more particularly to 'Figs.

5, 6 and 7, the main section 11 ofthe fold-i" ing .guideis formed of a strip. of metal,"

which, at the entrance end, follows a reverse eurvefrom the-top downward and thence extends upward-and again down to form a narrow curved channelffll, the end of the latter receiving theedg'e of the main fabric a The fabric being partlyintroduced,'with the movable section IQs'eparated from the main section, said movablesection is now moved up or closedand the fabric is forced by-the' vertically curved wall. ofsection 12, into engagement with the reversely curved portion 20. As the discharge or exit end of thegui'de is approached, the curved walls "gradually flatten until, asi-shown in Fig. 7,

the double henris formedand' the pocket is held open to facilitate the-introduction of the ruliierstrip' e.

A folding. guide comprising a base, guiding means-mounted on saidbase to fold the fabric back and forth upon itself, said guiding means includingsubstantially 'paral el-guiding walls one of which is movable relative to the other, said guiding means also having a guidin [space for-a secondpiece of fabric,- whic enters between the foldslof the body fabricjsubstantially as described. .i
